The Kessel Run is suppose to be about 18 Parsecs, which Han claimed to have done it in 12 Parsecs.

That would be the same as me saying I ran the 100 yard dash in about 66 yards, it's a ridiculous possibility that makes no sense unless I could bend time, like by jumping thru a worm hole... lol.

I think it's pretty obvious that Lucas did not do his homework on that one.

There are always explanations. Maybe it was a mistake. maybe not. Here's what they came up with(or not. Maybe it was intended as Lucas says here):

In Star Wars: Episode IV A New Hope, Han Solo boasted about the speed of his spaceship by claiming it made the Kessel Run in less than twelve parsecs, despite a parsec being a unit of distance. (In the novelization, he said, "less than twelve standard timeparts."[3]) Screenwriter George Lucas claimed the seeming gaffe in the film was intentional, showing that Han was something of a bull artist who didn't always know precisely what he was talking about.[4]

Within the Expanded Universe, Kevin J. Anderson later retconned an explanation: the Kessel Run is through the Maw. Event horizons around black holes are dependent on the speed at which you are traveling. A standard ship has to do the run in eighteen parsecs because to cut the route any closer, the ship would get sucked in. The Falcon, however, is fast enough to straighten the route and cut over six parsecs off the distance traveled.The director's commentary on the Blu-Ray Star Wars set explains that hyperspace travel requires heavy computation to compute a path that does not cause you to fly through a star. The Millennium Falcon has customized computation engines that calculate shorter hyperspace paths more quickly than those in other ships. Shorter distances mean faster travel times. The Falcon reduces travel times by a combination of being faster in a traditional sense, and by using more accurate navigation calculations.
